## What is IntervalGuide?

Your workout. Your rules. IntervalGuide is a fully customizable interval timer for
  HIIT, Tabata, boxing, and circuit training - built to work exactly the way you train.

  Design your interval workout block by block: set work and rest periods, add rounds,
  choose audio cues, and train in the right heart rate zone. Shake your iPhone to pause
  or resume - no need to touch the screen mid-round. Whether you're doing HIIT, boxing
  rounds, kettlebells, running intervals, or strength-training rest periods,
  IntervalGuide adapts to your routine, not the other way around.

  HANDS-FREE CONTROL
  Shake your iPhone to pause or resume - no need to remove your gloves, stop your set,
  or fumble with your screen. Perfect for boxing, kettlebells, winter runs, or any
  workout where touching your phone isn't an option.
